It is still not clear whether the effect of retirement on health is positive or negative. This column discusses new evidence from Japan showing that it is likely positive. In Japan, elderly people reduce their smoking and drinking after retirement. People tend to smoke and drink with their colleagues, so the result is mostly due to a peer effect.

Deflation is a threat to the macroeconomy. Japan had suffered from deflation for more than a decade, and now, Europe is facing it. To combat deflation under the zero interest bound, the Bank of Japan and the European Central Bank have resorted to quantitative easing, or increasing the money supply. This column explores its effectiveness, through the application of novel methods to distinguish signals from noises.

The productivity of a firm depends on its interaction with its suppliers and customers. This column uses unique data from Japan to investigate the wholesalers’ role in transaction networks, considering both sides of the transaction. The likelihood that a firm uses wholesalers increases with smaller buyer-side firms and larger seller-side firms. In addition, wholesalers tend to be located closer to their manufacturing buyers and further from their manufacturing sellers than manufacturers are to their direct manufacturing partners.

‘Learning by exporting’ refers to productivity gains experienced by firms after they commence exporting. Such gains are argued to be due to access to new knowledge and resources. This column explores some of the preconditions for learning-by-exporting effects, using data on the overseas activities and affiliations of Japanese firms. Firms that enter markets in which they don’t have affiliates or subsidiaries are found to enjoy the most learning-by-exporting productivity gains. These findings have implications for the timing of new market entry.

Corporate Japan is known for avoiding uncertainty. This is one of the reasons why changes of any kind are difficult – but not impossible – to realise. This column employs firm data to show that foreign direct investment has been changing corporate Japan by pursuing risk taking in private Japanese firms. This risk taking is positively related to firms’ sales growth and corporate earnings.

The two lost decades in Japan and the Global Crisis of 2007–2009 have created new opportunities for economic growth. This column describes the evolution of productivity across sectors in Japan and the US and suggests that the greatest payoffs for Japan would come from combining the Trans-Pacific Partnership with domestic reforms and encouraging foreign direct investment.

Japan was the first Asian nation to achieve modern economic growth. This column discusses new evidence suggesting that Japan’s growth started from a lower level than Britain’s and grew more slowly until the Meiji Restoration. The key to understanding modern economic growth seems to lie in identifying the forces that dampened growth reversals, rather than the forces responsible for growth itself.

Japanese firms have been struggling with the yen’s volatility ever since the peg was dropped in 1973. This column, based on a recent survey of Japanese firms, argues that many firms have managed their exchange rate exposure by using operational and financial hedging strategies. It also finds that firms employing currency hedge and invoicing exports in yen are judged by the market to have reduced currency exposures.

Japanese business groups, or keiretsu – cartels of companies with interlocking interests – have contributed much to the success of Japanese manufacturing in the 20th century. This column explores the future of this form of corporate governance, amid increasing calls for their dissolution. An examination of trade networks in the automotive industry shows that automakers no longer exhibit a preference for dealing with keiretsu partners. Globalisation, procurement scandals, and advances in modularisation have helped to erode the benefits of these long-term relationships.

World trade in services is increasing rapidly but micro evidence remains scarce. This column employs firm data from Japan to argue that service-exporting firms are more productive than non-exporting firms and goods-exporting firms. Information asymmetry, transportation costs, differences in institutions, cultures, and languages increase the fixed costs of service trade. Therefore, highly productive firms are more likely to self-select into service trade.

In order to achieve sustainable growth, Japan should make an efficient use of its labour force. However, female labour force participation and the share of women in leading positions in Japan remain low. This column investigates the impact of board diversity on firms’ innovative activity using Japanese firm-level data. The findings suggest that board diversity is associated with innovation only for firms that have already acquired diverse management skills.

Japan and Korea need to encourage female labour market participation to counter acute labour shortages. This column argues that following Nordic countries’ experiences, it would be possible to achieve both high female labour force participation rate and fertility rate. However, this is only possible if supported by appropriate public and private sector policies.

It seems like natural disasters should harm the economy by destroying lives and capital. This column investigates the extent to which disasters can lead to creative destruction through ‘natural selection’ of the fittest firms. Surprisingly, the rate of closure due to bankruptcy decreases – perhaps due to aid. Firm exits following the Tohoku earthquake were predominantly voluntary closures, with firms seizing the moment in order to leave an ageing market.

Despite vast improvements in information and communications technology, the tendency of firms in related industries to cluster together hardly changed between 1985 and 2005. This column examines the relationship between geographic clustering and innovation using establishment-level data from Japan. Research establishments – especially those in high-technology industries – are more localised than average. The degree of localisation is greater when establishments are weighted by their creativity, as measured by the number of patents created and the number of citations received.

While large Japanese firms have been present internationally for years, small firms have found it difficult to overcome the information obstacles associated with entering overseas markets. This column argues that lender banks can help as they not only provide financial support but also business consulting services using their extensive knowledge obtained through lending transactions. It shows that small and medium firms whose lender banks accumulate more overseas market information are more likely to start exporting.

A major concern with multinationals is that they can cause disemployment (also called job offshoring). However, FDI could offset or even exceed such a negative effect. This column examines to what extent disemployment in Japan is related to FDI. The results suggest that disemployment in Japan is driven by substitution between capital and labour, rather than the reallocation of labour caused by FDI.

The appropriate level of public sector wages is debated frequently in every country, and the debate has intensified in the wake of the global financial crisis. This column presents evidence that regional wage differentials in Japan are greater in the private sector than in the public sector. In regions where public sector wages are relatively high, skilled individuals may self-select into public sector jobs. At the same time, public sector employers in metropolitan regions such as Tokyo may have difficulty in hiring high quality employees.

In Japan, loans with 100% guarantees account for more than half of all loans covered by public credit guarantee schemes, but banks claim that they do not offer loans without sufficient screening and monitoring even if the loans are guaranteed. This column presents evidence of adverse selection and moral hazard in Japanese credit guarantee schemes. The problem is less severe for loans with 80% guarantees.

Many Japanese municipalities found recent population predictions for the next 30 years rather alarming. Unfortunately, most of them do not have an effective solution to the declining population problem. This column discusses different strategies that could ignite innovation and stimulate the growth of the population. Bringing in new business, identifying their comparative advantage, and stimulating community innovation could make municipalities attractive places to settle down.

Starting one’s working life in an irregular job can lead to a fruitful career or to long-term stagnation. While studies of European labour markets support the stepping-stone hypothesis, this column presents evidence that irregular jobs lead to negative midlife outcomes in Japan. Future jobs are less stable, pay less, and psychological distress is higher. Such problems suggest a role for policy to reduce economic and social disadvantages of non-regular workers.
